Pork Butt Thawing ?

internal temp isn't the issue, it's the external.

i grew up in a house where we'd leave the cooked turkey under foil overnight... hahaha

your concern is fecal bacteria on the SURFACE of the meat (there's no fecal bacteria IN meat) having a chance to multiply.

technically, if the surface of the meat (where the bacteria of concern are) is above 40 for longer than 4 hours, it is verboten. bacteria multiply faster at higher temps (room temp), and so it would be worse if the room were 65 or more.

that said, cryovac is anaerobic, and SOME bacteria don't grow well in that environment. but bacteria can grow just the same...

toguh call.

kids and older people eating it are probably a definite 'no'. healthy adults? if they have an iron stomach and don't mind the risk, have at it.

the nose knows. open it and smell. ignore the initial sulfurous cryo-smell.

bacteria will also make the meat feel very sticky-slimy, and won't rinse easily away. the smell will not rinse either (the cryo smell will rinse off, it's just a byproduct of the inert gas they seal it in).

You asked this question because you have doubts. When in doubt throw it out.

If you can truly get past your doubts, it most like will not hurt you to cook it. Me, I never get past my doubts when it comes to food and that Butt isn't all that expensive to replace.
